Posted:10th May 2002LOL! Ok, the toothbrush comes into it because if you swam 100,000 miles, well, that would take a long time, and assuming its salt water your swimming in, that cant be good for your teeth...Hygeine is an important issue children...wait its the enemy swimming....well, so he/shes an enemy?? so s/he will most likely be yelling at you for some reason?.. Imagin someone who has just swam 100,000 miles and hadnt brushed their teeth the WHOLE time yelling into your face! youd want minty fresh breath yeah??
